At Veltiston AI Greece, we are a passionate team of engineers building real-world AI and machine learning applications. Together with our colleagues at Veltiston AI Morocco, we form the Veltiston.AI Group, a cross-national organization that is steadily growing.


Our group was founded by Professor Dimitris Bertsimas of the MIT Sloan School of Management, who also founded Dynamic Ideas, a Boston-based company with over 25 years of history. Professor Bertsimas leads a broad ecosystem of companies, primarily based in Boston, which apply advanced Operations Research and Machine Learning across a wide range of sectors — including finance, supply chain, routing, revenue management, healthcare, legal, and education.


Within this ecosystem, Veltiston AI plays a central role as the AI and software development hub. We co-engineer advanced analytics platforms and decision-support tools that support innovation across various clients, portfolio companies, and domains.
